IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 47,775, dated May 16,1865.

. exactdescription of the construction and operation ofthe same, duereference`being had to the accompanying drawings.

Figure l represents a side view of a revolving pistol to which myimprovements are applied. Fig. 2 represents the front end of therevolving breech-cylinder and adjacentparts. Fig. 3 represents the rearend of the same.

To enable others skilled in the art to make and use my invention,Iwillproceed to describe its construction and operation.

A represents the revolving breech-cylinder, B the frame of the pistol, Dthe barrel, and C the hammer. rept esents the thimbles, which areinserted into the chambers of the cylinder A, and in using metalcartridges the charges are inserted into said thimbles, the objects ofthe thimbles being to facilitatethe removing of the cartridge-shellsafter the charge is tired.

E represents a stem whose diameter is equal to the inner diameter ofthethimbles t'. lt is attached to the barrelD by means of the sleeve K, andcan be turned thereon; but it can also be secured in its position to beeither in line with the chamber b or with the cha1nberc,Fig. 2, of thecylinder A. In the former case the thimble ofthe chamber b can be pushedupon the stem E afterthe charge has been tlred,and the stem E forces theempty cartridge-shell from within the thimble. The space between the endof the stem E and the face ot' the cylinder A must be sufficiently largeto permit of the insertion ofthe loaded cartridges into the chambers ofthe cylinder A when each is successively brought into the position ofchamber b. When the stem E is turned so as to be in line With thechamber c the thimbles can be removed I rom the cylinder A and from thepiece, it' it is desired to clean them, Without removing the cylinder A.In Fig. l one of the thimbles (shown in red lines) is represented on thestem E.

g represents a stud, which is secured to the angular spring-rod lz,Whose lower end is pro- Ward, as shown by red lines at Fig. 2. Theobject of the stud g is to prevent any acci-` dental displacementot'-the thimble when its chamber is in the position ot' chamber b, Fig.2,as in this position the thimbleis not retained in its chamber by anypart ofthe frame B, as is .the case in any other position,andwhen thethimble is to be pushed upon the stem E the knob J is pressed inward andthe study releases the thimble.

' O represents the notches in the rear face of the cylinder A, throughwhiclrthe front end of the hammer C passes to explode the cartridges.

0 represents another series otnotches, which are made on the rear faceof the oylinderAin such a position that the latter is looked by thefront edge ofthe hammer at a point when the chamber b of the cylindercomes tothe position where the loaded cartridge can be inserted, thusmaking the cylinder self-adjusting and greatly facilitating theoperation of loading. 'lhese notches serve at the same time to lockthehamlner to preventthe accidental discharge ot' thepiecewhenit is notto be used; but their principal use bengthe setting of the cylinder Afor charging, their location is not discretionary, but for that purposemust be at certain points.

Having thus fully described the nature of my invention,what I claimherein as ne\v,and desire to secure by Letters Patent, s

The application to the barrel of revolving fire-arms of a hinged stem,E, for supporting the thimble and clearing itwhen removed from thecylinder A, substantially as and for the purposes described.
